There was an interview recently (a year or two?) on Speak Easy????? And Al mentions he drinks "once a month". Whether that's one drink or one day, who knows. He could even be lying about once a month! He was drinking on the show (The girliest drink they could muster, which was a strawberry... daiquiri? cobbler???).

Does Suzanne drink? Maybe his once a month privilege is to chill out with her.

I don't know that TPP limits fair use, not to say I support the TPP in any way, however the examples given by that redditor are not at all cases of fair use, and it seems like they have a limited understanding of what it constitutes. Having said all of that, fair use is protected by the First Amendment, not an international treaty, so it is highly unlikely that fair use as it pertains to a music parody artist would be affected.
